Highlights
The Okeanos Aggressor II liveaboard was built for comfort and stability to offer year-round diving at the remote islands of Costa Rica. The yacht provides comfortable accommodation for 24 guests in 12 en-suite cabins. Eight deluxe staterooms are located on the lower deck, and there is a double lower bed and twin upper bunk-style bed. On the main deck is the master stateroom with a queen bed, and on the upper deck are two suites that have either two twin beds or one king bed.
On the main deck is the ship's restaurant, where delicious cuisine with a varied and plentiful menu is served. Breakfast and lunches are buffet-style, and dinner is chef-prepared and served each evening. On the top deck is the BBQ and shaded cocktail bar, perfect for unwinding with fellow guests to discuss the spectacular diving of the day. Here, you can also find comfortable loungers to do some tanning in between dives.
The Okeanos II liveaboard departs from Puntarenas, Costa Rica for the 36-hour crossing to Costa Rica. Guests can enjoy up to 21 dives at the UNESCO World Heritage site for the chance of big fish encounters like nowhere else. Aside from the incredible diving, guests will also be taken ashore to hike through the jungles of Cocos and swim in the many waterfalls.

Great option for cocos!
The crew was very friendly and accommodating, food was excellent. Dives were safe and enjoyable. This is a great option to see cocos and more budget friendly than the alternatives.

Truly a once in a lifetime experience.
Unbelievable diving with bunches of sharks at every site. Because we were at the end of the dry season there was little rain and calm seas making for a pleasant crossing and opportunities to visit the island. Can't say enough about the crew, they are dedicated to making your experience an enjoyable one.

Trip of a lifetime
The diving exceeded expectations, the crew was so hospitable and went out of their way to make sure we lacked for nothing, and the food was the best I've ever had on a liveaboard. The only criticism, is that the boat's common areas could use a little updating.

Perfect sport for shark lovers
Cocos Island is a fantastic option for shark lovers due to the variety you can find at each dive. It is a long trip from Costa Rica but completely worth it. The crew did a great job to make sure we all felt comfortable. Special mention to the chef and his assistant, who amazed us every day with fantastic dinners.

As good as indonesia on some dive sites
some sites had several schools of different kinds of fish, as well as sharks and turtles, all in one dive. I like to watch schools of fish. I have been to Indonesia on many dive vacations and Cano Island is as good as Indonesia for schooling fish on some dive sites.

PuraVida in this JurassicPark like environment
What a special island, and a special feeling to be lucky enough to have been there. Crew was amazing, dives were warm and with good viz, many hammer heads around, eagle and marble rays, dolphins etc... although the best season apparently ranges from August to October, with colder waters and loads of sharks. PuraVida !

A journey through time and space
The trip to Cocos Island in Costa Rica aboard the Okeanos Aggressor II was unforgettable. With a friendly, helpful and knowledgeable crew of the operation, we were able to visit this magical destination that transports one in time and space. On the trip we shared with people from several countries around the world in a very pleasant atmosphere, being able to visit fantastic diving spots where we saw multiple species of pelagic animals from the Pacific Ocean.
